To enhance Mandatory Garbage Sorting (MGS) Policy and recycling performance, on-site consultant service for implementation agencies (Chai-Yi county and Yunlin county), household garbage sorting investigation, recyclable flow investigation, enterprise non-hazardous business waste recycling promotion and promotion proposal were implemented. From project implementation outcomes, the difficulties of sorting household waste lied in insufficient space, unable coordinating time and complicated sorting modes. Therefore, we should focus on educating and insuring the concept of sorting trash into three main categories. It could save space and time and simplify the ways of sorting to raise the will of sorting. Regarding on recyclable flow investigation, 51 recyclers, who bought recyclables from 169 implementation agencies by Fixed-Price-Single-Contractor model and Various-Prices-Single-Contractor model, were interviewed on-site. We found an increase of Single-Contractor model tenders that shared 70% and 23% of total implementation agencies number in 2004 and 2009, respectively. The project also found that only 54% recyclables were delivered to registered processor and the rest 46% recyclables were sent to unregistered business. The main problems that Single-Contractor model recyclers usually encountered included low percentage of high value recyclable (37.3%), high percentage of low value recyclable (47.1%), and high residual percentage (41.2%), instability of recyclable volume (33.3%), no available legal processors/techniques (19.6%), low recyclable market price (9.80%) and unfixable tender recyclable price (27.5%). It demonstrated the necessity for intensive control of recyclable flow and more compressive tender rules when implementation agencies sold recyclable. The project also found that there were basic recycling facilities for refuse in most enterprises. The main defects were management and measures were not established and practiced. Therefore, the government should assist the enterprises to establish and implement the management mechanisms for improving the recycling of refuse in enterprises. The following topics were recommended for an higher recycling and mandatory garbage sorting achievement (1)continues enforcing Keep Trash Off the Ground requirement, (2)improve implementation agency recycling efficiency, (3)strict management on recycle flow and (4)encourage enterprise to recycle refuse.
